I wanted to test the compatibility of some programs so I tried installing OS X Mavericks on a Fennec Hackintosh System and a laptop. The Fennec Hackintosh System went easily (due to a missing CR2032 battery which reset the date) but the laptop had problems as its battery was installed. After comparing the two systems, I found the only difference was the system date and was then able to install it successfully on the desktop, the laptop, and in the Virtual Machine environment. Below are resources I hope will aid you in doing the same.
1. I grabbed a copy of OS X from the Internet. (2 hours over Wi-Fi)
2. I followed the tips in creating a USB Installer. (20 minutes)
3. I then use the release date workaround to install successfully. (45 minutes)
4. I completed the Fennec Hackintosh System.
With Mavericks now installed, this gave me access to download Yosemite, El Capitan, and all the later releases that follow.
